PCP overview

Introduction

The following sections provide you with a reference to PCP

location to help you install or replace PCPs.

Note: This manual sometimes refers to PCPs as “cards.”

EC 11 printed circuit

packs

The EC 11 uses the following PCPs:

• NT6P97AA Enhanced MMP40 or MMP40 CPU card

• NT6P42AA Utility card

• NT6P08AA VP8 or NT6P04AA VP4 voice processor

cards

• NTDK36AA Meridian Mail bus terminator card in a

one-node EC 11 (also in a two-node EC 11 with 32 or

fewer ports)

Note: Only the voice processor cards are hot-pluggable. That

is, you can remove or insert voice processor cards while the

power to the module is still on. It is recommended, however,

that you power down the module prior to removing or

inserting the voice processor cards. For removal without

powering down, you must first disable the voice processor

cards using the “System Status and Maintenance” function on

the administration terminal. See the System Administration

Guide (NTP 555-7001-301) for details on disabling cards.

CAUTION

Risk of equipment damage

Wear an antistatic wrist strap when

handling components or cables, or when

working on the backplane. As an

additional safety measure, handle

components by the edges and, whenever

possible, with the loosened packing

material still around the component.
